Each heart contraction begins in a small group of cardiac muscle cells called?
The sinoatrial node is the small group of cardiac muscles that initiates each heart contraction.
Small group of cardiac muscle cells that sets the pace for the heart?
the sinoatrial node; located in the right atrium.
The difference between the structure of cardiac muscle and skeletal muscle?
One key difference between cardiac and skeletal muscles is that skeletal muscles are controlled by the nervous system, while cardiac muscles move involuntarily. In addition, cardiac muscles are only found in the heart, while skeletal muscles are found throughout the entire body.
What is the function of the peacemaker?
a small group of cardiac muscle cells that "set the pace" for the heart as a whole and they begin each contractions.
Is there is a small amount of smooth muscle in the heart?
No. and cardiac muscle is technically different from skeletal muscle, too.
What is cardiac tissue made up of?
Cardiac tissue is made of cardiac muscle cells and a small amount of connective tissue. The cells that make this tissue are called cardiocytes. They have the special ability to "beat" on their own with no nerve stimulation. If one touches another beating cell, they will begin to beat together. In the heart some group will form a pacemaker to provide a rhythm for the organ.
Why are skeletal muscle cells multinucleated?
The number of cells depends on how large the muscle is; muscles consist of fiber bundles, which are made up of myofibrils. A sarcomere is one of the segments that the myofibril is divided into. In each fiber bundle there are multinucleate cells, which can extend the length of the skeletal muscle. So, the number of cells in a skeletal muscle depends on the size of the muscle. for example, the number of cells in one of our triceps larger than one of the small muscles in a finger.
What does a flagellum of a muscle cell do?
Muscle cells do not have flagella. Flagella are for a cell's or small organism's movement.
How are checks and muscle cells different?
the checs are small and the muscles are big
Which structure is located between the esophagus and the stomach?
The sphincter muscle, or ileocecal valve is located at the junction of the small and large intestine.
What role does muscle tissue play in the heart?
Cardiac muscle is the foundation of the heart. Cardiac muscle is an involuntary muscle meaning that it works on its own. You engage it like you would an arm or a let. The cardiac muscle has a built in system allowing it to be virtually fatigue resistant. This is because cardiac muscle is loaded with mitochondria which are a cell's power house or power plant.
What is noun cluster?
